The Volkswagen ID.3 has no other secrets for you regarding autonomy after the first part of Supertest. It remains to be seen how it behaves in front of fast charging stations and on long distances with this second part.
In order to shed light on electric cars and their consumption, we decided to conduct life-size tests, studying each model to travel almost 2,000 km. An opportunity to measure the autonomy on the long distances on the highway, but also the mixed consumption and the recharging possibilities in the fast terminals. For this, we have implemented a strict protocol for each car.

Volkswagen ID.3 charging curves: a “useful” full in 33 minutes
Apart from the slow charging capital, where Volkswagen can not compete with the Megane e-Tech, it has a fast DC charging power of 120 kW. This is just 10 kW less than in the Renault spec sheet. According to the brochure, the recharge time from 5 to 80% is 35 minutes. In fact, ID.3 keeps all its promises and more: 5% off, compact quickly rises to power 131 kW ! This is the maximum we could observe during the test, at a Fastned terminal and without having activated the battery preheating.
This is followed by a charging curve with a profile shaped according to the other curves we have observed, although with higher power values of 2 kW at most in the intermediate SoCs. The power peak unfortunately does not last, but the high forces are maintained up to 20% before forming the first step. It is from the 25% that the curves of our complete recharge met. However, despite the slightly lower power, the recharge times are similar to the minute.
Finally, recharging 10-80% of the Volkswagen ID.3 requires 33 minutes with great precision. When it is cold, with a maximum power of 107 kW at 10%, the same type of charge will only need 1’30 ” more. It is not enough to change the life of a driver on a long journey. Especially because they will rarely fill up at a fast charging station early in the morning before leaving. At this 70% load, Volkswagen gained an average of 41.9 kWh according to the display of the terminals or 40.6 kWh according to the strict rule of three taking into account the useful capacity of the battery. The difference is small.
DC fast charge curves
The curve forms a final plateau between 70 and 80%. From there, it will take 10 minutes more to reach 90%. Overall, the total time is just under 59 minutes to complete a 10-100%. The percentage of hunting has its limits on the highway since, to go into details, with ID.3 you lose almost 20% in 43 km, of which 2% is consumed only leaving the rest area.
Typical recharge curve
Autonomy was restored: 157 km in 30 minutes
According to our measurements, the Volkswagen ID.3 has a total range of 243 km, or 170 km of useful range. In a fast terminal, it is therefore able to regain 170 km of autonomy in 33 minutes. Always from SoC 10%, you will be able to gain 97 km in 15 minutes throughout the lap, while it will take almost an hour to calculate on a 218 km freeway.
As far as autonomy is concerned, the screen is linear in its announcements, but still a bit optimistic. According to theoretical calculations, according to all measurements of our highway, it is based on an average consumption of 21.7 kWh / 100 km. In fact, this corresponds to a difference of autonomy of at most 10 km. Difference that decreases as the battery charge drops: there is a difference of 7 km at 20%, 3 km at 10% and 2 km at 7%. Therefore, the SoC / autonomy ratio seems rather reassuring.
Autonomy recovery / recharging time
How much do Volkswagen ID.3 recharges cost?
Volkswagen has the advantage of being part of the consortium of manufacturers gathered around the Ionity charging network. With the compact, drivers can take advantage of preferential rates through the We Charge badge, which provides access to more than 250,000 charging points in Europe. There are three types, specifically the We Charge Plus offer at € 9.99 / month in the first year and then at € 17.49 / month. In this case, the price at Ionity terminals drops to 0.30 € / minute.
That is, the 10-80% supplement costs only € 9.90, ie. direct cost 5.82 € / 100 km. Rather attractive for highway travel, especially in view of the full price of € 0.79 / minute, which would raise the bill to € 26.07 (€ 15.34 / 100 km). But this case must be taken into account, as the signal provided by Volkswagen was not recognized at the Ionity station in Maison-Dieu, for example.
Also, the We Charge signal was not accepted at Fastned terminals. Fortunately, if we had a backup Chargemap, they also offer the ability to pay directly by credit card. According to the information reported by the terminal, the exercise represents a charge of 41.5 kWh, or € 24.49, or cost € 14.41 / 100 km.
For this trip on the A6 motorway to the south / north direction, we had to complete three times for a net amount (excluding operator fees) € 45.41. This is a total cost of € 10.56 / 100 km before our last stage (distance 430 km). As usual, we do not calculate the cost price over 500 km, as it is the price of the last recharge to find the starting SoC that will determine the total cost.
Built-in route planning, ABRP and ChargeMap: ABRP pioneers (slowly)
Last exercise of this Volkswagen ID.3 Supertest Clean Automobile, the comparison of route designers. Available on the main screen, German electric navigation is particularly enjoyable. Takes the trouble to warn that the destination is out of range of the remaining autonomy and displays an equidistant map of the radius of action.
From our starting point, choose the A7 and A6 motorways that serve as our base to reach the Porte d’Orléans in Paris, the finish line of our trip. With 80% charge available, enough to get to the Fastned station at regulating speeds, however, the designer prefers the Ionity terminals, necessarily a Total station. In the end, it provides for three stops for 1h17 recharging (a total of 6h25 with travel times).
The A Better Route Planner application is equally fond of Ionity terminals, with stops at the three major stations along the way. But having a better database with this vehicle, the recharging times are quite close to reality, while it makes us reach the stations with 10% of the charge remaining (except that of Tapona). In short, according to him, they need 4h42 road and 51 minutes of recharging for a total of 5h33.
ChargeMap manages to target the Fastned station in Saint-Ambreuil and the Ionity terminal in Maison-Dieu, but takes us via the Total station in the Couline area. Total functions: 47 minutes of recharging and 4h20 on the road (total 5h07). Again, in a few minutes the cooldowns are more or less real. Minus the SoC forecasts upon arrival at the terminals. This is evidenced by the first forecast, where the ChargeMap system predicts 23% on arrival at the Fastned station.
In fact, we got there with a 7% charge left. First completion up to 70%: 27 minutes. Enough to gain enough to reach the Maison-Dieu area, where we achieved 12-70% in 25 minutes. Finally, last recharge at Ionity terminal near Nemours with 11 minutes of immobilization.
In the end, our strategy based on the Renault Megane e-Tech model that was scrutinized a few days earlier, results in a 4h22 and 1h03 recharge trip for 500 km. Adding the time of developments in the areas, our trip represents 5h37. In the case of the Volkswagen ID.3, the A Better Route Planner seems closer to reality. The ChargeMap is not far behind, but its slightly overly optimistic first estimate has overturned charging times. Otherwise, the SoC / mileage ratio is closer to what we have actually observed. Certainly, this method of calculation is not very strict, but it is the one that speaks most to the neo-enlightened.
What is Supertest?
Lovers of numbers and allergic to official data sheets, Supertest, Automobile-Propre’s new test format, is made for you, collecting data collected during a real-time test in accordance with a transparent and accurate protocol. Next Wednesday we will publish a new summary article allowing comparison of the prices recorded for the models tested, which will make all the value of the unit.
